Some girls from my past have had those. You pee on them and it tells you if its positive or negative charge. Must work because they always seem shocked.

Sure great, but what if they start leaking?

"That would dramatically change the dynamics of road trips"
fluid dynamics, you mean?

Finally, guys can start tasting like 9 volt batteries, too!

I'm told it recharges fastest with Hello Kitty pee.

I pee on my employees to get them working again. That seems to work.

I understand you can buy DVDs of ladies recharging batteries. This is what I have been told.

Great. Our grandchildren will think a good prank to pull on someone will be to put gas in the pee tank. The more things change...

I'm no scientist, but fshaw. You guys are actually falling for this?
From the Reghardware link:
"It’s rumoured the batteries retain their charge for up to 10 years, but they can be recharged only a limited number of times."
Thinking that these things are somehow carrying significantly more potential chemical energy than a traditional battery is, in my opinion, probably about the same as thinking that hydrogen cars can just magically run on water.
Water is about the most stable molecule on the planet, no? I.e., it doesn't have much potential chemical energy to release. So whatever energy is released is coming from the "mixture of magnesium and carbon." (Also Reghardware)
While it may "retain its charge" for ten years, that charge is . . . wait for it . . . about the same charge as any other battery.

I just thought of something that else can be recharged with the addition of pee: Your lovelife!

This reminded me of a story in the Weekly World News about Japanese people drinking their urine for health. I believed everything they ever printed.

OK, someone has to spoil the fun. The urine is the electrolyte, not the anode or the cathode, and so does not actually "power" the cell.
On a related note, Metafilter's own Bill Beaty discussed the limitations of the "lemon battery" here.

Yeah, isn't it actually urine activated, not urine powered?

Give me a few beers and at the end of the night, damned right my urine will power generators. Fit turbines on guys as they enter bars, and no doubt the disco lights will stay on to the wee hours.
